Does anyone know?

SOrry, not sure, but I have a feeling there is a specific one it should be one.

I always thought it was the left leg

My gut instinct would be the left leg too (probably cos I'm left handed/legged??) but I just googled it and a few websites are saying the right leg.

Don't think it really matters.

Id be lucky to find one that fitted my thigh!!! I aint gonna bother, terrified it slips down around my ankle!

Anyone else got any idea?

No idea and couldn't even tell you which leg I had it on! Probably my right - just know it ended up on hubby's head by the end of the night!!

I think it is the left.

I put mine on the left leg and after the wedding we went out into the hotel garden to have our pics taken and the best man came up to me and said your garter is round your ankle. Don't know how he noticed as I had a long dress one and I never felt is slip down. We have a pic with him putting the garter round his wrist. That was after i declined his offer to put it back on my thigh!
